Metallurgy Matters Making steels stronger - The Fabricator

Oct 09, 2003 · Austenitizing temperatures higher than 1,800 degrees F generally cause a coarse austenitic grain structure, and these coarse-grained steels are usually inferior to fine-grained steels in terms of strength, ductility, and toughness. Steel forgings and castings are often normalized specifically to refine their grain structure.
